25 (((
26
27
28 Dragino NSE01 is an (% style="color:blue" %)**NB-IOT soil moisture & EC sensor**(%%) for agricultural IoT. Used to measure the soil moisture of saline-alkali soil and loam. The soil sensor uses the FDR method to calculate soil moisture and compensates it with soil temperature and electrical conductivity. It has also been calibrated for mineral soil types at the factory.
29
30 It can detect (% style="color:blue" %)**Soil Moisture, Soil Temperature and Soil Conductivity**(%%), and upload its value to the server wirelessly.
31
32 The wireless technology used in NSE01 allows the device to send data at a low data rate and reach ultra-long distances, providing ultra-long-distance spread spectrum Communication.
33
34 NSE01 are powered by (% style="color:blue" %)**8500mAh Li-SOCI2**(%%) batteries, which can be used for up to 5 years.

109
110 (((
111 The NSE01 is equipped with a NB-IoT module, the pre-loaded firmware in NSE01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by NSE01.

128
129 === 2.2.1 Test Requirement ===
130
131
132 To use NSE01 in your city, make sure meet below requirements:
133
134 * Your local operator has already distributed a NB-IoT Network there.
135 * The local NB-IoT network used the band that NSE01 supports.
136 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
137
138
139 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NSE01 will use CoAP((% style="color:red" %)120.24.4.116:5683)(%%) or raw UDP((% style="color:red" %)120.24.4.116:5601)(%%) or MQTT((% style="color:red" %)120.24.4.116:1883)(%%)or TCP((% style="color:red" %)120.24.4.116:5600)(%%)protocol to send data to the test server

158
159
160 User need to configure NSE01 via serial port to set the **(% style="color:blue" %)Server Address** / **Uplink Topic** (%%)to define where and how-to uplink packets. NSE01 support AT Commands, user can use a USB to TTL adapter to connect to NSE01 and use AT Commands to configure it, as below.
161
162
163
164
165 Connection:
166
167 USB TTL GND <~-~-~-~-> GND
168
169 USB TTL TXD <~-~-~-~-> UART_RXD
170
171 USB TTL RXD <~-~-~-~-> UART_TXD

177 * Baud: **9600**
178 * Data bits:** 8**
179 * Stop bits: **1**
180 * Parity: **None**
181 * Flow Control: **None**

183
184 Make sure the switch is in FLASH position, then power on device by connecting the jumper on NSE01. NSE01 will output system info once power on as below, we can enter the **password: 12345678** to access AT Command input.

The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.

945 You can change the battery in the LSE01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.

949 The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)

1099 How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.

1115 For example, in **US915** band, the frequency table is as below. By default, the end node will use all channels (0~~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~~71) to send uplink packets.

1121 When you use the TTN network, the US915 frequency bands use are:
1122
1123 * 903.9 - SF7BW125 to SF10BW125
1124 * 904.1 - SF7BW125 to SF10BW125

1128 * 904.9 - SF7BW125 to SF10BW125
1129 * 905.1 - SF7BW125 to SF10BW125

1134 Because the end node is now hopping in 72 frequency, it makes it difficult for the devices to Join the TTN network and uplink data. To solve this issue, you can access the device via the AT commands and run:

1157 == 4.2 ​Can I calibrate LSE01 to different soil types? ==
1158
1159 LSE01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/LSE01/&file=Calibrate_to_other_Soil_20220605.pdf]].
